A machining center for performing a plurality of machining operations, such as drilling, milling, cutting, using rotating tools, on metal profiles having a longitudinal extent greater than their cross-section dimension, particularly but not exclusively made of aluminum. The machining center comprises a base defining a work surface extending longitudinally with first and second ends, upon which the profile is manually laid by an operator or by a specially-designed automatic feeder. The base has a plurality of members thereon for supporting and locking the profile, as well as a pair of vertical columns for supporting motorized spindles, each column being located next to said base and being configured to being displaced in either direction, parallel to the longitudinal extent of the base along respective slide guides located next to said base. Each vertical column is equipped with a first carriage configured to vertically sliding in either direction along its respective column and with a second carriage mounted to the first carriage, and configured to sliding in either direction perpendicular to its respective column. The center also comprises a portal structure whose upper beam above said base is equipped with a motorized spindle for rotating tools, mounted to a support body configured to angular displacements around a pivot for rotating about a first axis parallel to the longitudinal extent of the base.

A machine tool comprises a main spindle, a tool post body provided with a first tool mounting part and a second tool mounting part facing each other with a workpiece inbetween in a predetermined facing direction, and a tool post body driving unit for moving the tool post body in at least the facing direction. The tool post body comprises a first tool post unit provided with the first tool mounting part, a second tool post unit provided with a portion of the second tool mounting part with a relative interval with respect to the first tool post unit in the facing direction kept constant, a third tool post unit provided with the remaining portion of the second tool mounting part with a relative interval kept variable; and a relatively-driving unit for moving the third tool post unit in the facing direction with respect to the first tool post unit.

The invention relates to a machine tool as well as to a method for operating the machine tool. The machine tool comprises a workpiece carrier (20) that can be incrementally rotated about an incremental advance axis (22) and has several carrier sides (25). A first workpiece chuck unit (26) for holding a workpiece in a first position (P1) and a second workpiece chuck unit (27) for holding a workpiece in a second position (P2) are arranged on each carrier side (25).
